Record confirms

TxDOT’s San Antonio district project page lists a proposed expansion of FM 3351 between I-10 and SH 46, covering portions of Kendall, Bexar and Comal counties.

Why this matters

Public question

How will road expansion affect drainage, access, safety and development pressure?

Possible local levers
